The Sun Hydraulics RSHCLWV (RSHCLWV) is a pilot-operated, balanced piston sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This valve regulates pressure at port 1 relative to the drain port 3, remaining unaffected by back pressure at port 2 up to its set value. It can replace 2-port relief valves in systems with return line pressure. All three-port sequence cartridges are interchangeable in terms of flow path and cavity for a given frame size. As the inlet pressure at port 1 rises above the valve setting relative to drain port 3, pilot flow increases. The main stage orifice is safeguarded by a 150-micron stainless steel screen. The pressure at port 3 adds directly to the valve setting on a 1:1 ratio and should not exceed 5000 psi (350 bar). This model is unsuitable for load-holding applications due to spool leakage. The RSHCLWV utilizes Sun's floating style construction to reduce internal binding risks from excessive torque or cavity machining variations. It features adjustable controls (W and Y) across its full range unless a special setting is specified, which then represents the maximum setting. The valve has a capacity of 60 gpm (240 L/min), with factory settings established at 4 gpm (15 L/min). Its maximum operating pressure is rated at 5000 psi (350 bar), with control pilot flow between 15-20 in\u00b3/min (0.25-0.33 L/min) and typical response time of approximately 10 ms. Maximum leakage at specified conditions is limited to 4 in\u00b3/min (65 cc/min). The RSHCLWV weighs approximately 1.50 lb (0.70 kg) and requires specific installation torque specifications for optimal performance, including an adjustment screw internal hex size of 5/32 inches and locknut torque between 80-90 lbf-in (9-10 Nm).
